In an alternative universe, when Sasuke left the leaf village, the Hokage decided to put an end to this ninja dick-measuring contest and confiscated everyone's ninja stars. Fast forward a couple years, and Naruto's a mess. He got a sex change to cope with the whole "no ninja" policy. Now she's trying to move on from the past the only way she knows how - getting drunk and having her pussy pounded in a public park.
Alright actually, this hentai's just a bunch of short stories where couples have sex in an office, at a park, at a maid cafe, you name it. There is a chick called Naruto however, and that alone makes it pretty damn hilarious.
